High Cliff State Park is a 1,187-acre (480 ha) Wisconsin state park near Sherwood, Wisconsin. It is the only state-owned recreation area located on Lake Winnebago. The park got its name from cliffs of the Niagara Escarpment, a land formation east of the shore of Lake Winnebago that stretches north through northeast Wisconsin, Upper Michigan, and Ontario to Niagara Falls and New York State.
